[4A] 這張齒輪圖紙的技術說明，你能看出哪里需要完善？

十年一夢

大家討論一下有什么需要完善之處。

機械神話

希望看到這張圖，機械圖紙是圖文并存的，不可分離。

這是你自己出圖紙給鬼佬加工的？

- G/ z' Q2 H; u5 D/ o材質應寫入材質欄，這里只要寫熱處理方式和最終硬度
2. CENTERS ARE MANDATORY ON BOTH ENDS OF SHAFT. ALL DIAMETERS MUST BE MACHINED USING THESE CENTERS AND -A- & -B- DIAMETERS MUST BE CONCENTRIC TO THESE CENTERS WITHIN 0.005 TIR.
這里的軸可能用axis比較合適，因為這根軸線不是實際存在的東西，同軸度本身就是個跳動值所以不用TIR。更應該直接標在圖上。
3.DYNAMICALLY BALANCE WITHING 0.26 OZ-IN AT PLANES INDICATED INSTALL HALF-KEY IN THE KEYWAY DURING BALANCING.
半鍵連接？動平衡因該在整根軸帶齒輪的裝配體完成后整體做的，把這個要求寫在這里應該要REF一個裝配圖要求。

沒有圖紙怎么分析啊？樓上有圖紙了？

無圖無真相另，另外還要說一下功用。

高手啊，三樓

樓主你這應該是單個零件的技術要求吧？我覺得第三條動平衡應該去掉，單個零件的在這沒什么用；第五條磨削余量沒必要寫在這個里面吧，畢竟是工藝要求；另外，你要求表面刀紋看不出，那就直接定個粗糙度Ra1.6以下，這個可去參考粗糙度標準樣塊；第十條未注同心度0.254你有和第三條校核沒？單位是英制還是公制？有必要到小數點后三位？還有最后那條不太清楚你要干什么。
